shmoverride test fix2.1-pre1
The shmoverride tests currently hang when run as a user. This is because the cleanup routine tries to reset the nr_hugepages value to what is was at the beginning of the test. This will fail with bad CONFIG which will try and call cleanup again. This patch initialises saved_nr_hugepages to -1 and does not restore the value in cleanup if it is <= 0.
